DENI SVG is a highly effective rod lock for the lock side of windows and French windows.

Slim aluminium profiles with high quality treated surfaces are available in four standard colours and many possible special colours. Moreover, they impress with their visual unobtrusiveness on the sash.

The rod lock is activated by the normal use of the window handle. While the window is closed, the bolts are driven out both up- and downwards. That way, the extended bolts provide two additional safety points.

The special feature, in particular, is:
Also in the tilted state of the window DENI SVG remains partly active.
Thus, the lower bolt stays extended downwards. Considering the fact that, according to statistics, more and more burglaries take place during the day and while people are in the house, this special tilt protection provides a higher level of protection. The levering out of the sash window while a room is ventilated becomes significantly more difficult for the perpetrator.

Niederhoff & Dellenbusch GmbH & Co. KG is a medium-sized, family owned business located in Heiligenhaus, in the region of North Rhine-Westphalia, Germany. Under the brand name DENI® the company sells a wide range of closures and fittings for doors, gates, windows & interiors.
